Answer 1

You can use delattr(class, field_name) to remove it from the class definition.

Full example:

# python 3
class A:  
    def __init__(self):
        self.field_to_keep = "keep this in B"
        self.field_to_delete = "don't want this in B"

class B(A):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        delattr(self, 'field_to_delete')
